颗粒阻尼是一种很好的轻量化结构被动阻尼技术，但其复杂的尺寸确定过程阻碍了其广泛的应用。在本文中，提出了一个多级设计工具链，使系统的设计和尺寸过程的颗粒阻尼器。从而将各种数值模型和实验测试相结合。这开始于单粒子碰撞的微观力学行为的调查。接着分析了容器内颗粒物质的振动特性，最后设计了一种理想结构的阻尼器。良好的协议的模型和他们的效率的阻尼器的设计和尺寸最后证明了在一个弹性的轻型机械手进行水平，瞬态振动。使用此设计工具链，利用球体的滚动属性，引入了一种用于低振幅振动的新的且更有效的阻尼器设计。通过将颗粒阻尼器分成几层，实现了弹性轻量化机械臂的高阻尼。
Particle damping has become a favorable passive damping technique for lightweight structures, however, its complex dimensioning process hinder its wide use in technical applications. In this paper, a multilevel design tool chain is presented to enable a systematic design and dimensioning process of particle dampers. Thereby various numerical models and experimental tests are combined. This starts with investigations of the micro-mechanical behavior of single particle impacts. Continuing, with analyzing the properties of vibrated granular matters inside a container and ending with designing a damper for a desired structure. The good agreement of the models and their efficiency for the damper design and dimensioning are finally demonstrated on an elastic lightweight manipulator undergoing a horizontal, transient vibration. Using this design toolchain, a new and much more efficient damper design for low amplitude vibrations is introduced using the rolling attribute of spheres. By separating the particle damper into several layers, high damping of the elastic lightweight manipulator is achieved.
